Understanding Gravitational Potential Energy

What is gravitational potential energy primarily dependent on?

• Mass and speed

• Volume and density

• Height and gravity

• Temperature and pressure

What happens to potential energy as an object moves down a ramp?

• It increases

• It remains constant

• It converts to kinetic energy

• It disappears completely

Why does an object eventually stop moving on a track?

• Because it runs out of potential energy

• Due to the absence of gravity

• Due to an increase in mass

• Because of energy loss through friction and sound

In an open system, what happens to energy?

• It remains unchanged

• It can be lost

• It is destroyed

• It is created

What role does friction play in the movement of an object on a track?

• It increases the object's potential energy

• It has no effect

• It causes energy to be lost as heat

• It speeds up the object
